    dct:description "The gravity station data (9,050 records), were observed and processed by the Instituto Geografico Agustin Codazzi(IGAC), in Colombia from 1958 to 1996. This data base was received in April, 1997. Principal gravity parameters include Free-air anomalies and both Simple and Complete Bouguer anomalies. The gravity anomaly values were computed using the GRS80 ellipsoid." ;
